A plurality of rib 401 extending from an upper edge of the ring flange 400 is formed to the inner wall of the retaining sleeve 40 with a predetermined gap between. A groove 402 is formed between adjacent ribs 401. A sloping guide 403 is formed to an upper end of each rib 401. All the sloping guides 403 slope toward a same direction. A plurality of retaining slot 404 is formed to an upper end of the retaining sleeve 40.

The retaining block 41 has a plurality of buckle 410 on a peripheral thereof for being embedded into the retaining slots 404 of the retaining sleeve 40. The retaining block 41 has a threaded hole 411 penetrating from a top to bottom thereof.

The lead screw 42 is arranged through the threaded hole 411 of the retaining block 41. Two spacing surfaces 420 are formed oppositely to a peripheral of the lead screw 42.

The lipstick holder 43 is arranged to a top of the lead screw 42 and is rotatable. The lipstick holder 43 is inside the upper case 11 and a bottom of the lipstick 2 is placed on the lipstick holder 43.

The axial pusher 44 is hollow and a plurality of protruding guide 440 is formed to an upper peripheral of the axial pusher 44 so that the plurality of the protruding guide 440 can be slid into the grooves 402 of the retaining sleeve 40. Two slopes 441 extend from a central top of the protruding guide 440 towards adjacent protruding guides 440 respectively. The bottoms of the slopes 441 of adjacent protruding guides 440 are connected together.

The rotary slider 45 is arranged inside the retaining sleeve 40 and above the axial pusher 44. The rotary slider 45 has a through hole 450 on a top thereof for being penetrated by the lead screw 42. The through hole 450 has two positioning surfaces 451 for blocking the two spacing surfaces 420 of the lead screw 42 so that the lead screw 42 can only slide along the through hole 450 without rotating in the through hole 450. A plurality of clutch 452 is formed around a peripheral of the rotary slider 45, and the clutch 452 is slid into the grooves 402 of the retaining sleeve 40. An oblique slide 453 is formed to a lower end of each clutch 452. The clutch 452 can slide along the slope 441 of the protruding guide 440 and along the sloping guide 403 of the rib 401 by the slide 453.
